5 Claims.

The object of the present invention is to provide a container which can be shipped in flat form, which can be used advantageously as a substitute for drums, barrels, tubs, pails, kits and baskets as customarily made, which will be cylindrical when placed in completed form, permitting the use of tight-fitting circular heads and enabling the lining of the containers with various materials or compounds such as paraffin, silica of soda, latex, paper, pulp, etc., which may be constructed of veneer, plywood, paper-board, or combinations of these materials; and which is formed without any overlapping.

One of the elements of the container is a scam in continuous strip form, in one or a plurality of parts, the strip or strips being formed with teeth which may be pressed through the material of the container.

These and other features of the invention will be described with reference to the accompanying drawings, in which:--

The problem which was overcome by my invention was the provision of container elements including seam and head elements which enable the formation of the container body in flat form with longitudinal seam closure member or members attached thereto and in such simple form as to be readily operated to form a completed tubular body in conjunction with base and head-holding elements of equally simple character, yet strong and rugged in construction, and adapted for quick attachment.

Referring to Figures 10 and 11, I have therein shown a body piece I in fiat form which may be made of veneer, plywood, paper-board or other suitable flexible and preferably springy material. At the left-hand end thereof and extending vertically is a seam-closing staple strip 2, a fragment of which is shown in Figure 3A. The staple strip 2 is formed with a locking flange 2x and is V-cut, the metal being bent outwardly to form the staple teeth.

At its right-hand end the body piece l carries a staple strip 3 bent to form a longitudinally extending hook flange 3:0 connected to the main portion of the staple strip by a channel at 33:90.

The staple strip is V-cut at spaced points and the metal bent outwardly to form the staple teeth t. The staple teeth of each staple strip are driven into the appropriate margin of the container body piece and the teeth are then bent over as shown in Figure 3.

In forming the cylindrical body of the container, the body piece I is bent in annular form to bring the staple strips toward each other and the hook flange 3 of one staple strip is interlocked with the flange 2m of the second staple strip in the manner shown in Figure 3. This will leave the edges of the strip spaced, and when the interlocking structure is pressed downwardly to final position as shown in Figure 12, the edges of the body piece will be brought toward each other and into firm mutual contact as shown in said figure if the ends of the strip are sufliciently close together. The body strip being of relatively yielding material, the drawing action. of the staple strip will efiect such compression at the seam as to afford a satisfactory leak-proof joint.

The base of the container may be closed by the instrumentalities shown in Figures 1, 2 and, i. In

the said figures a base disk 4 is pressed downwardly within a metallic ring centrally formed with an inwardly projecting bead 4m, in such manner that an area of the ring will project above the disk. This area is then spun or pressed downwardly to form a top locking flange 5. Below bead 4a: the ring may continue as a vertical depending extension and, if desired, the base of the ring may be outwardly bent at 6 to form an abutment wall for the base of the container body. Over upon the depending vertical extension of the beaded ring may he slipped a plurality of channeled locking clips I, each clip near its upper end being V-cut and the metal bent in to form staple teeth Ix, which teeth are pressed into the container body and preferably bent over onto the inner face thereof, as indicated in Figure 4. In some cases, it will be then desirable to form each clip with spaced beads which may receive between them a reinforcing hoop preferably formed of wire as shown at 8, and at the point where the hoop meets the interlocked staple strips, the lat ter may be grooved to receive the hoop as indicated at the base of Figure 2.

In Figure a modified form of base construo-' tion is shown in which the disk 4 and its immediate holding member 5 are of the same con- 'struction as that shown in Figure 4, and hence bear the same reference characters.

When the base disk is inserted into the lower end of the tubular body it is held in position by a plurality of spring clips 9 cut to provide one or more prongs II] which may be pressed into the outer face of the container body. Thus each clip 5 is similar to that shown in Figure 4, except that it omits holding means for a ring such as 8.

The top of the container may be closed by a closure member I I shouldered to abut the top of the container body.

The top closure for the container may be of the construction shown in Figures 9 and 7. In

that case, the closing disk II is moved within a deeply channeled and beaded ring I2, the channel being adapted to receive an upper margin of the container body. The closure disk will be abutted with a bead I21: of ring I2 and thereupon the lower margin of the ring at the point I2zra: will be bent or spun down upon the closure disk to hold it in position. The staple teeth I3 of the ring may be driven into the wall of the container as shown in Figure 9. In practice, the vertical area of the channel ring carrying the teeth I3 may be spread outwardl so that the teeth may lie in their usual transverse position relatively to the channel and be driven into the body of the container by compression of the channel area of the ring against the opposite faces of the container body.

To enable ready removal of the container closure and replacing thereof and, at the same time, provide means for holding the closure firmly in position, the channel ring may omit the staple teeth and in lieu thereof be formed with a plurality of slots to receive the upper and bendable sections of a plurality of holding clips l lzcr, as shown in Figures 6 and 8. Each clip is preferably formed with a plurality of staple teeth driven into the wall of the container and when the closure disk is in position the upper ends of each clip may be bent over into locking position, as shown in Figure 8.

In Figure 13 I have shown a longitudinal seamconnecting staple strip similar to that of Figure 12 in that the member 2 is the same as the corresponding member of Figure 12, the locking extention is bent back upon itself at its juncture with the hooked portion thereof to impart greater rigidity to the structure, the hooked portion be ing indicated at Ida: and the said staple strip as a Whole being indicated at I4.

In certain types of light gauge containers the longitudinal seam may consisting of a simple band as shown in Figures 6 band being formed with a plurality of V-cuts and are headed over onto the inner face thereof.

In heavier types of container bodies, each longitudinal margin may carry a staple strip I6, Figure 15, reversely bent to form a hook, the hooks of the two strips lying opposite each other and adapted for connection by a double flange-connector strip I1.

is applied and given compression toward the container body the parts will assume the position shown in Figure 1, if the ends of the container body are sufliciently close Having described my invention what I claim and desire to secure by Letters Patent is as follows:
